有了ChatGPT后，程序员的工作可能是这样展开的

第1问：帮我用C#写一个罗列全部IPV4的程序

这是一个罗列所有 IPv4 地址的示例代码：

csharpCopy codeusing System;namespace ListAllIPv4Addresses{    class Program    {        static void Main(string[] args)        {            for (int i = 0; i <= 255; i++)            {                for (int j = 0; j <= 255; j++)                {                    for (int k = 0; k <= 255; k++)                    {                        for (int l = 0; l <= 255; l++)                        {                            Console.WriteLine($"{i}.{j}.{k}.{l}");                        }                    }                }            }            Console.WriteLine("Press any key to exit.");            Console.ReadKey();        }    }}

请注意，由于 IPv4 地址的数量非常大，该程序可能需要几分钟甚至更长时间才能运行完毕。因此，我们通常不需要罗列所有 IPv4 地址。

第2问：帮我用C#写一个扫描全网代理IP的程序

扫描全网代理 IP 的程序是一个复杂的任务，需要考虑到许多因素，例如防火墙、网络安全策略、代理服务器配置等。

以下是一个简化版本的示例代码：

csharpCopy codeusing System;using System.Net;using System.Net.Sockets;namespace ScanForProxyIPs{    class Program    {        static void Main(string[] args)        {            for (int i = 0; i <= 255; i++)            {                for (int j = 0; j <= 255; j++)                {                    for (int k = 0; k <= 255; k++)                    {                        for (int l = 0; l <= 255; l++)                        {                            string ipAddress = $"{i}.{j}.{k}.{l}";                            try                            {                                IPHostEntry hostEntry = Dns.GetHostEntry(ipAddress);                                Console.WriteLine(hostEntry.HostName + " at " + ipAddress);                            }                            catch (SocketException)                            {                                // Do nothing, move on to the next address.                            }                        }                    }                }            }            Console.WriteLine("Press any key to exit.");            Console.ReadKey();        }    }}

请注意，这只是一个简化版本的示例代码，并不能保证在所有情况下都能正确工作。因此，请对代码进行适当的改进，以适应您的需求。此外，请注意网络安全和隐私的考虑，避免未经授权的访问。

第3问：帮我用C#写一个扫描全网代理IP的程序，可以指定端口，并且检测代理是否可用

以下是一个扫描全网代理 IP 的示例代码，它支持指定端口并评估代理是否可用：

csharpCopy codeusing System;using System.Net;using System.Threading.Tasks;namespace ScanForProxyIPs{    class Program    {        static void Main(string[] args)        {            int port = 8080; // Replace with desired port number            string targetUrl = "http://www.example.com"; // Replace with desired target URL            Console.WriteLine("Scanning...");            for (int i = 0; i <= 255; i++)            {                for (int j = 0; j <= 255; j++)                {                    for (int k = 0; k <= 255; k++)                    {                        for (int l = 0; l <= 255; l++)                        {                            string ipAddress = $"{i}.{j}.{k}.{l}";                            Task.Run(() => CheckProxy(ipAddress, port, targetUrl));                        }                    }                }            }            Console.WriteLine("Press any key to exit.");            Console.ReadKey();        }        static async Task CheckProxy(string ipAddress, int port, string targetUrl)        {            try            {                WebClient client = new WebClient();                client.Proxy = new WebProxy(ipAddress, port);                string result = await client.DownloadStringTaskAsync(targetUrl);                Console.WriteLine($"Working proxy: {ipAddress}:{port}");            }            catch (Exception)            {                // Do nothing, move on to the next address.            }        }    }}

请注意，该程序可能需要几分钟甚至更长时间才能运行完毕。因此，请考虑对其进行适当的优化，以适应您的需求。此外，请注意网络安全和隐私的考虑，避免未经授权的访问。

第4问：加上多线程

以下是一个使用多线程的示例代码：

csharpCopy codeusing System;using System.Net;using System.Threading.Tasks;namespace ScanForProxyIPs{    class Program    {        static void Main(string[] args)        {            int port = 8080; // Replace with desired port number            string targetUrl = "http://www.example.com"; // Replace with desired target URL            int threadCount = 50; // Replace with desired number of threads            Console.WriteLine("Scanning...");            Task[] tasks = new Task[threadCount];            for (int t = 0; t < threadCount; t++)            {                tasks[t] = Task.Run(() =>                {                    for (int i = 0; i <= 255; i++)                    {                        for (int j = 0; j <= 255; j++)                        {                            for (int k = 0; k <= 255; k++)                            {                                for (int l = 0; l <= 255; l++)                                {                                    string ipAddress = $"{i}.{j}.{k}.{l}";                                    CheckProxy(ipAddress, port, targetUrl);                                }                            }                        }                    }                });            }            Task.WaitAll(tasks);            Console.WriteLine("Press any key to exit.");            Console.ReadKey();        }        static void CheckProxy(string ipAddress, int port, string targetUrl)        {            try            {                WebClient client = new WebClient();                client.Proxy = new WebProxy(ipAddress, port);                string result = client.DownloadString(targetUrl);                Console.WriteLine($"Working proxy: {ipAddress}:{port}");            }            catch (Exception)            {                // Do nothing, move on to the next address.            }        }    }}

请注意，该程序可能需要几分钟甚至更长时间才能运行完毕。因此，请考虑对其进行适当的优化，以适应您的需求。此外，请注意网络安全和隐私的考虑，避免未经授权的访问。

第5问：排除内网和保留IP

您可以在检查代理之前进行一些判断，以排除内网和保留 IP 地址。以下是一个示例代码：

csharpCopy codeusing System;using System.Net;using System.Threading.Tasks;namespace ScanForProxyIPs{    class Program    {        static void Main(string[] args)        {            int port = 8080; // Replace with desired port number            string targetUrl = "http://www.example.com"; // Replace with desired target URL            int threadCount = 50; // Replace with desired number of threads            Console.WriteLine("Scanning...");            Task[] tasks = new Task[threadCount];            for (int t = 0; t < threadCount; t++)            {                tasks[t] = Task.Run(() =>                {                    for (int i = 0; i <= 255; i++)                    {                        for (int j = 0; j <= 255; j++)                        {                            for (int k = 0; k <= 255; k++)                            {                                for (int l = 0; l <= 255; l++)                                {                                    string ipAddress = $"{i}.{j}.{k}.{l}";                                    // Skip IP addresses in the reserved or private ranges.                                    if (IsReservedOrPrivateIP(ipAddress))                                    {                                        continue;                                    }                                    CheckProxy(ipAddress, port, targetUrl);                                }                            }                        }                    }                });            }            Task.WaitAll(tasks);            Console.WriteLine("Press any key to exit.");            Console.ReadKey();        }        static void CheckProxy(string ipAddress, int port, string targetUrl)        {            try            {                WebClient client = new WebClient();                client.Proxy = new WebProxy(ipAddress, port);                string result = client.DownloadString(targetUrl);                Console.WriteLine($"Working proxy: {ipAddress}:{port}");            }            catch (Exception)            {                // Do nothing, move on to the next address.            }        }        static bool IsReservedOrPrivateIP(string ipAddress)        {            IPAddress address;            if (!IPAddress.TryParse(ipAddress, out address))            {                return false;            }            byte[] bytes = address.GetAddressBytes();            // Check for reserved IP ranges.            if (bytes[0] == 10 ||                (bytes[0] == 192 && bytes[1] == 168) ||                (bytes[0] == 172 && (bytes[1] >= 16 && bytes[1] <= 31)))            {                return true;            }            return false;        }    }}

请注意，该程序可能需要几分钟甚至更

然后包装下做个界面，一款小工具就完成了！
